Description

Technical Field

[0001] The utility model relates to the technical field of forging auxiliary equipment, in particular to a heat treatment device for a nickel-based alloy forging. Background Art

[0002] Heat treatment furnace refers to an electric furnace or fuel furnace used for heat treatment of furnace charge. Commonly used heat treatment furnaces include box-type resistance furnaces, pit-type resistance furnaces, gas carburizing furnaces and salt bath furnaces. Continuous furnaces are usually used. Workpieces are continuously loaded from the loading door and continuously unloaded from the discharge door after passing through the furnace. The commonly used method of conveying in the furnace is that the workpiece is carried on a heat-resistant steel guide rail and transferred by a stepping moving beam or push rod. The heat treatment furnace has the characteristics of a large temperature range, strict furnace temperature control, reduced metal oxidation and decarburization, and low productivity and thermal efficiency. After the existing heat treatment furnace is heated, the temperature of the metal surface is still high, which is not convenient for manual timely removal for subsequent processing, affecting production efficiency.

[0003] A forging heat treatment furnace with the publication number CN215481115U comprises a bottom plate, a box body is arranged on the top of the bottom plate, a mounting assembly is arranged on the top of the bottom plate, which penetrates and extends into the inside of the box body and is movably connected to the left and right sides of the inner wall thereof, a heating assembly is arranged on the left and right sides of the inner wall of the box body and the top of the inner wall thereof, and an adjusting assembly is arranged inside the mounting assembly, which is respectively fixedly connected to the left and right sides of the inner wall of the box body. The forging heat treatment furnace starts a double-axis servo motor, which drives the winding wheel to rotate, so that the pull rope is tightened or stretched. When the pull rope is tightened, the pull rope drives the movable rod to move backward, so that the left and right connecting blocks move backward. Since the installation box is fixedly connected to the bottom plate, and the box body is movably connected to the bottom plate, the connecting blocks drive the box body to move backward at the same time, until the box body moves to the leaked part of the installation box, at which time the forgings inside the installation box can be taken out, achieving the purpose of easy taking.

[0004] The above technical solution has some problems in practical application. Although the forging can be pushed out of the device after heating, the forging still needs to be picked up and transferred using an additional clamping device after being pushed out of the device, which is still inconvenient for subsequent processing of the forging.

[0005] Therefore, it is necessary to invent a heat treatment device for nickel-based alloy forgings to solve the above problems. Utility Model Content
